rlhe compartments thus formed are preferably filled with silk floss, but cotton or other materials may be used ir. desired. Or.-

dinarily no tutting Whatever is used. but

conditions may arise when it Will be desirable to run a row of tui-'ting along the lines A--B or C-D, or both.

We have also provided on the long sides et this mattress the strips l5 securely fastened to the ticking of the mattress for the purpose of handling same, since it would be quite difficult to do so otherwise in the absence of a rolled edge.

Since it is found in practice that the maj or portion ot the labor charge'in the construction ot mattresses is madeup by tufting and edge rolling, it will be observed that we have` eliminatedboth ofthese operations, as yell as the machines for performing same, thereby tremendously reducing,` the manuifaJturing` Acost oif 'the mattress, [and yin addition thereto have constructed a mattress With a wonderfully uniform top `and edges,vvhich can safely beguaranteedto hold its shape 'lor the lite of the fabric from lwhich it is constructed.

4in the use ot certain materials for v.filling n; Winnen, or roe'rnann,

it may prove expedient to run one ortwo Y rows oi stitchingil across the tivo center lines il .and C D olf the mattress in order'to prevent collapsing oll thel mattress when shipped it is desirable to eliminate all tuft in the ordinary sense of the Word, inasmuch as aside from the` expense of in* stalling, it must also be. accompanied by in 'nn-the sizes` of ticking to make up for the nat". "ial in the tufts, and the tufts when i'iulled down tightly furnish concealment tor dust and vermin. It mustbe understood that this stitching or lacing `is not drawn down tight usare tufts, but is loose enough to permit the cover to sprcadthe full height ot the sides. @ne continuous thread is used to serv clear across the mattress in Zig zag fashion and the thread issecured only aty the ends.

lt will be understood that mattresses havebcen manufactured employing one dividing sheet and includingv tutting; We are able 'to ldispense with` thel tufting and `to increase the resiliency ci the mattress byincreasingl the number of dividing;` sheets, for the fol- 'y lowing; reasons: Each sheetproduces a friction with the y filling' proportional to the weight i above same. Consequently the Agreater the number of horizontal sheets, the

greater the resistance to lateral movement byy the filler. until the point is reached Where even the tendency of shitting of the liller is overcome. After thisv point is reached it is not profitable to addmore sheets, sincethe vost increases out of proportion to theadln additionto this, there is still another advantage in themultiple sheet mattress. This is the distribution of strains between all of the sheets Whichv are` also held by the same friction of the filler,

have been Whereas il only one dividing sheet is used, there is not sullioient friction to withstand the outward pull on the sheet.

The added resilience is clue to the feet that this Construction has produced a` number of superimposed hannnoeks held in suspension7 partially by the side Walls and partially by the friction between 'the sheet and the yiiller beneath and above seine rather than being supported bjf the resilience of the liller itself'.

le are were Vthat numerous mattresses Constructed along somewhat lines. We therefore do not Claim our invention broacllj7 but onlj)7 Within the limits set forth in the following claims.

VVhat-We claim as new is:

l. An untuif'ted mattress Without rolled edges having a loose iillinp; and having :i plurality of stretehless horizontal dividing ineens between its top and bottom and zitteohecl by their outer edges to the sides of the mattress, seid dividing ineens and seid top and bottoni having exactly ythe saine size7 seid cliif'icling ineens being sulioient in nuinbei to prevent the shifting ofthe filling `Without the use of tufting.
